We have had a lot of moisture in the past week, but the last few days have been dry in most parts of the state. This has led to lower risk scab prediction. But some parts of the state in the central and east have moderate levels of scab prediction. If there is a lot of dew on leaves in morning, infection can still take place. Scab can be managed by applying a triazole fungicide within 3 days before flowering and 6 days after flowering.
